Key value for chemical safety assessment
Additional information
The LC50 of threrephthalic acid (100 -21 -0) is stated to be highrer than 961mg/l, the one of hexamethylene diamine (124 -09 -4) is >=1000 mg/l and the tetramethylene diamine (110 -60 -1) is 730 mg/l. Endpoint. As set out in the waiver this unequivocally supports the conclusion that fish are likely to be less sensitive than algae and aquatic invertabrates. The toxicity levels of the diamine ions contained in the submission item to aquatic invertabrates and algae are about an order of magnitude lower than the toxicity to fish. This endpoint data are available from the ECHA dessemination page as of October 19, 2017.
